Company history

Marsh & McLennan Companies traces its roots to early 20th-century brokerage and consulting firms that merged and evolved into a multi-brand professional services group. Over decades, the company expanded through acquisitions, building a set of specialized subsidiaries focused on insurance brokerage, reinsurance advisory, human-capital and investment consulting, and strategy and management consulting.

Origins and early years

The firm’s heritage includes major early brokers and consultancies established in the early 1900s. Over time, Marsh & McLennan became a holding company structure that grouped Marsh (insurance broking), Mercer (employee benefits and investment consulting) and other specialist businesses under one corporate umbrella. This structure allowed Marsh & McLennan to offer clients an integrated set of risk, insurance and advice services across industries and geographies.

Expansion and acquisitions

Through the late 20th and early 21st centuries, the company grew by acquiring complementary businesses and expanding internationally. Notable expansions built out the Marsh brokerage network, established Guy Carpenter as a reinsurance advisory leader, and strengthened Mercer’s human capital and investment consulting offerings. The acquisition and retention strategy created a multi-brand portfolio that serves large corporate clients, governments and institutional investors.

Business model and segments
